Anywhere in your code do you have a line like this: app.use(); without parameters? If so, app.use() actually requires multiple parameters and a callback, it should be formatted as so:
// This is what it should look like
app.use(function (req, res, next) {
console.log('Time: %d', Date.now());
next();
});
//Note you don't have to use 'next'
app.use(function (req, res) {
console.log('Time: %d', Date.now());
});
also note that you don't need to explicitly use req or res but you need to add them as parameters.

Treehouse Moderator 11,077 PointsCan you provide your code? It would be much easier to help you out if I could see your code.
